SLIDING-DOOR HANGER.

SPECIFICATION formingpart of Letters Patent No. 721,819, dated March 3,1903.

Application filed July 1'7, 1902. Serial No. 115,962. (No model.)

To all whom, it may concern:

Be it known that I, JOHN F. MILLERICK, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inSliding-Door Hangers; and I do hereby declare the following to be afull, clear, and exact description of the invention,such as will enableothers skilled in the art to which it appertains to make and use thesame.

My present invention is an improvement in that class of devices known inthe art as sliding door hangers and is designed for its greatersimplicity of construction and efl:i

ciency and certainty of operation.

The device possesses all the requisites of strength and durability andis so improved generally as to render it capable of supporting all sizesof sliding doors regardless of their Weight. 4

Other objects and advantages of the inven-. tion will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

I am enabled to accomplish'the above results by the means illustrated inthe accompanying drawings, in which Figure 1 is a side elevation of apair of ordinary sliding doors, showing my invention positioned relativeto one of them. Fig. 2 is a perspective view of the several arms attheir point of union.

I will now set forth the construction of the several parts of myinvention and subsequently explain the operation of the same, referencebeing had to the above views by letter.

A A represent a pair of ordinary twin sliding doors adapted to slide insuitable pockets in the walls.

Pivoted to the rear edge B of the door at points near the upper andlower edges thereof are the rigid twin arms C and D, while atcorresponding points on a rear vertical stud S are pivoted the similararms C D, their free ends being pivoted to the free ends of the arms Cand D at the points a and 1). Connecting these pivotal points a and b isthe vertical rod R. Now in order to add to the strength and efficiencyof the device I have provided the arms E and E, pivoted to the door andstud, respectively, while their inner ends are pivoted to a smallroller, which is adapted to travel in the Vertical slot (1, formed inrod B. This small roller I have shown in dotted lines in Fig. l. thedoor is opened the arms C, C, D, and D will swing upward, while the armsE and E swing downward. Closing the door reverses this action of thearms. In cases where the door is extremely heavy it is myintention toplace a roller G at the lower rear corner of the door, as shown in Fig.1.

A great objection to the use of this general class of hangers has beenthe liability of the arms canting, and consequently binding in thepockets. In my device I overcome this fault by providing the rollers Mand M, which guide the arms away from contact with the pocket.

I am aware that various changes in the form and proportion of parts ofthe devices herein shown and described as an embodiment of my inventioncan be made without departing from the spirit or sacrificing any of theadvantages thereof, and I therefore reserve the right to make suchchanges and alterations as fairly fall within the scope of my invention.

Having thus fully described my invention,

*what I claim, and desire to secure by Letters Patent, is--' 1. A deviceof the class described consisting of a series of parallel arms pivotedto the back edge of the door, and a similar series pivoted to a verticalstandard back of the door, the meeting ends of opposite series be-- Itis manifest that as ing pivoted to a central vertical rod, and oppositearms at an angle with said former arms and having their meeting endsslidably connected to said central rod substantially as and for thepurpose set forth.

2. Adoor-hanger consisting of an upper and a lower series of extensibleand retractable arms, a vertical rod connecting the meeting ends of saidarms, a third series of arms at an angle with said other series and slidably connected to said central rod, and a roller on said rod to preventcanting of said arms substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN F. MILLERICK.
